Hey guys!

Just to start the post, I've actually done my research as to parameters, tank size, tank mates and the like, so all this should be alright, though i'm still going to explain the plan and the questions will fall into place. :)

Also, I usually write long posts, so for people who don't feel like reading my wall of text, i've put my questions in bold. :)

I've redone my 800L (180g) to be just sand, pieces of wood and epiphyte plants for a matamata.
I've done research as to what particular fish I could put with that turtle that would'nt get eaten and actually come from the same dark water, biotope, and I've settled for Discus and geophagus. This also meant I had to double the filtration because discus get sensitive, or so I've heard.

Discus because well, they're gorgeous, and quiet. But also because like the geophagus, they get big enough that the matamata won't be looking at them.
Geophagus because I heard discus are messy eaters, and I couldn't do the usual corydoras bottom feeders because of the size.

There remains a few questions in my plan, and while I got someone for the matamata part of it, discus are a whole new world for me.

I'm going to be needing to add the discus first, that way the tank is going to be the quarantine while I grow the matamata in a smaller enclosure to lean it towards dead food and can add it once the discus are settled.

Budget wise, it'd be easier for me to get smaller discus, we all know that, baby fish cost less than full grown adults, and it's even more so for discus. Are they fast growers? Can I expect them to outgrow the matamata's growth?

Also, I would love to witness the true parental care, would that be able to happen in a "community" tank? Granted it's just discus and geos, the matamata won't even look at baby discus until they're big enough to be scooped out. I was told it can happen, but don't know if it's the exception rather than the norm.

For number, does 10 sound good in that tank? 15? Less? More?
It's probably the only fish I feel can make a tank stand out without needing a whole lot of them.
To add to that, less bioload the better, while I will have 5000L/h filtration, I have no idea how messy they are so I don't want to overcrowd. And let's be completely honest, I want room for those +1 or +2 you see in that store you'd never seen before and MUST_BUY_NOW. :D

Last but not least, if any of you have pictures of discus in a dark water setup, I wouldn't mind seeing that, I know what they look like in normal pristine looking water, but in dark, copperish water, it might (and should) look completely different.

Thanks in advance, I'm getting more and more excited about this. :D
 
Research I've done on Discus is small Discus will not grow if quality of living conditions aren't kept at the highest standards.

I feel overfiltration, with more room than for twice the number of what I want should be plenty enough good condition. :) Did I miss something?

No just wanted add the info of starting with the small Discus vs Larger Discus.

Ahhh, makes sense. I heard I need 30°C for them too. But since they'll be alone, I can cope with that and go down to 28 once they're bigger and the matamata comes in.

Discus require tanks to be free of debris buildup and bacterial growth, you will be doing a LOT of cleaning with a turtle involved. A friend has about 15 in his 750l and he cleans that tank daily.

I'd be worried about the turtle possibly scaring the discus, they stress rather easily. You'll have to grow discus out for quite some time for them to be large enough. I'll ask my friend what he thinks :)

Matamata don't move much, they're ambush predators, I don't think it'll scare them at all. It's not a FRT or anything of the sort. It basically sits where it feels comfortable, and it almost invisible anyway, so seeing it will be hard for the fish.

That's good then. I'm not educated on the waste levels of turtles, but make sure to keep your filtration and tank spotless.

Tannins will help with immunity, but take no risks. When the water is clean discus are not that bad :)

In a 180, you will need a heck of a lot more than extra filtration - with a turtle in the tank you will become a slave to water changes, and that's with a species of turtle much smaller than what a mata mata will eventually reach. The geos will also outcompete the discus when it comes to eating. Eventually the turtle will most likely start killing all fish in the tank. Turtles and fish do not generally pan out very well, for the fish. Eventually large carnivorous turtles will take bites out of larger fish, and swallow whole smaller fish that more easily fit in their mouth.

IMO an all around very bad mix for a discus set up, even in a tank 3 times that size. Good luck.

I'm actually in contact with Chris, who gave me all the necessary infos about the mata. He didn't seem to think discus would be a problem. This was his take on tankmates:
"As far as tank mates, they should be larger than what they can eat. Discus work well, and angel fish, I had both at one point with mine. The only draw back to them is when it comes to feeding. If you can't get them to switch to frozen food, you will have no choice but to feed live. The cheapest and most economical way to achieve that in the US is to go with bait fish. Which usually carry diseases that could potentially spread to your ornamental fish. This happened a few times with my angel fish. So you have to be careful. Hopolo catfish are too small and will quickly become food. Even for a small one. If not food, they could harm the turtle. Geos should be fine for a while. By the time they get too small, they should be smart enough to know to stay away. "

And well, if I lose one, I always have a 90g to rehouse them, I just don't want to get to that because I want them in the living room.

My biggest concern is: would small discus grow faster that a mata does? Just to make sure I can take them small and ensure that they remain out of mata maw size range.
